Though I wonder what was the original intent of handling
GOTO_EXPRs. Devang?

I started writing this pass to understand what you guys
were doing in tree-ssa branch. At that time, I did not
immediately figured that GOTOs are implicitly encoded in
CFG. CFG is, at that time, available only at RTL level was
my initial (obviously wrong :) impression. And some how,
this code escaped until now.
